While cosmological-scale isotropy is an elemental working assumption in cosmology, multiple observations using different probes have shown evidence of large-scale anisotropy. In addition to the anisotropy in the cosmic microwave background (CMB) [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, large-scale anisotropy has been reported by analyzing the distribution of short gamma ray bursts [8]}, Ia supernova [9]}, [10]}, LX-T scaling [11]}, \(H_o\)  [12]}, dark energy [13]}, [14]}, [15]}, [16]}, high-energy cosmic rays [17]}, quasars [18]}, [19]}, and the frequency of galaxy morphology types [20]}. Another specific observation that violates the cosmological isotropy assumption is the existence of the CMB Cold Spot [21]}, [22]}, [23]}. A correlation between higher \(H_o\)  and the CMB dipole has also been reported [24]}, [12]}.
